I te pāmahana rūma, he paura mā, he tioata pakarukaru rānei, ka wairewa ki te wai me ngā whakarewa waro pēnei i te formaldehyde, te etanoru, te acetone, te tetrahydrofuran, te etilasetate, te acrylonitrile, te styrene, me ētahi atu. He tino ngāwari te hanga i te polymer mā te copolymerization me ngā momo monomer, ā, ka kaha te mimiti wai, engari kāore e wairewa ki te ethane, te petroleum ether.
E rua ngā rōpū tauhohenga a DAAM, arā, ko ngā amide kua whakakapia ki te N me te ketone, he tino ngāwari te whakakotahitanga me ētahi atu monomer vinyl, nō reira, mā te whakaurunga o ngā āhuatanga matū ketone carbonyl ka taea te arahi i te polymer ki te tauhohenga whakawhiti me te tauhohenga whakapiri, ka taea te whakarite i ngā momo piripiri, te whakamātotoru, te kaihoko whakapakari pepa, te kaihoko whakawhiti, me ētahi atu.
Kua whānuitia te whakamahinga i roto i ngā mara pēnei i ngā paninga, ngā piripiri, te ahumahi matū o ia rā, te kaihoko whakaora kapia epoxy, ngā tāpiringa kapia photosensitive, ngā āwhina kakahu, te tiaki hauora, me ētahi atu.
1. Kaiwhakaora makawe:
Ko tētahi āhuatanga nui o te DAAM ko te kore e wairewa tōna homopolymer, tōna copolymer rānei i roto i te wai, engari ka taea e tōna tere mimiti wai te eke ki te 20% ~ 30% o tōna taumaha, ina iti iho i te 60% te haumākū o te taiao, ka taea e rātou te tuku i te makuku, kātahi ka taea te whakaputa i te rehu makawe mā roto i taua āhuatanga.
2. Kapia whakaahua-ātete:
Ko te kapia whakaahua-ataata i hangaia mai i te diamine homopolymer totoka e ātete ana ki te mārama, te mārō, te waikawa me te kawakore, he tere tere te whakaahua o te kapia, he ngāwari te tango i te wāhanga kāore e pāngia i muri i te whakaaturanga, kia puta ai he tahora pepa mārama, he kaha pai, he ātete hoki ki te wai.
Ko tētahi atu whakamahinga nui o DAAM ko tōna āheinga ki te whakakapi i te gelatin, e whakamahia ana mō ngā whakapūtanga whakaahua, ā, he uaua ki te whakakapia e ētahi atu hua pai. Kua roa te korenga o te gelatin mō te parakore o te whakaahua, e 2500 tana o te gelatin e tumanakohia ana mō ngā rauemi whakaahua-ā-ahua, engari ko te hanga gelatin whakaahua ā-rohe he rau tana noa iho i tēnei wā.
3. Whakamahia mō te whakarite i te tānga reta kirihou
4. Whakamahia mō ngā piripiri:
e whakamahia ana hei whakatairanga piripiri me te whakapai ake mō ngā matū muka, te sima, te karāhe, te konumohe me te PVC, i taua wā ka taea hoki te kōpeke hei whakaputa piripiri tairongo-pēhanga, ā, ka taea hoki te whakamahi hei piripiri tairongo-wera mō te pepa, te kakahu me te kiriata kirihou me te allyl polymer.
5. Te whakamahinga i roto i ētahi atu āhuatanga:
⑴ ka taea te whakamahi hei rongoā mō te kapia epoxy, te peita ārai-waikura o te raro kaipuke, te peita raro wai o te raro kaipuke, ngā paninga kapia kiriaku, te peita polyester kore-mākū, me ētahi atu;
⑵ I whakamahia pai te monomer copolymer wairewa-wai o DAAM ki te whakamārama i ngā totoka i whakatārewatia;
⑶ Ka taea te whakamahi hei rauemi tuhi taiaho i hangaia e te wera;
⑷ Whakamahia hei tango i te karāhe mōhinuhinu;
⑸ Whakamahia hei hanganga o te kapia whakaahua-wairewa-wai;
⑹ Whakamahia mō ngā peita wairewa-wai.
